GAS-BURNER, ATTACHMENT.

Application filed August 6, 1921.

T all whom it may concern Be it known that 1, WILLIAM R. GARDNER, a citizen of the United States, and resident of the city of New York, in the county of l'iew York and State of New York, have invented certain new and useful Improvements in Gas-Burner Attachments, of which the following is a specification.

My invention relates to improvements in to gas burner attachments, and the object of my invention is to produce a cheap and simple device which can be easily applied to any ordinary gas burner, and which will confine, condense, and direct the heat waves so that they will impinge upon the article to be heated, with the result that heating can be effected with a great economy of gas. Where gas burners are used in the ordinary way, as on gas ranges for heating various articles, a great deal of heat is lost by radiation; but my invention is in the nature of a flexible short ring or funnel which can be adjusted as to length. easily fitted to the burner beneath the grid, and thus will prec5 vent the flames and heat waves from spreading, and direct them upon the article above. My invention is also intended toproduce a device of this character which can be instantly adjusted and firmly secured so as to 80 fit any ordinary burner, and in which the lower part of the device is provided with air holes through which atmospheric air may enter to assist in supporting combustion at the burner, with the result that the 85 necessary amount of heat required at the object being heated can be had with much less consumption of gas, than where the gas is burned in th ordinary way. All of which will be better understood from the description which follows.

Reference is to be had to the accompanying drawings forming part of this specification, in which similar reference characters indicate corresponding. parts in all the 4s views.

Figure 1 is aperspective View of the gas saver attachment embodying my invention.

Figure 2 is a plan view of the device as applied to a burner, and

Figure 3 is a cross section of the attachment as applied to a burner.

The condensing apparatus embodying my invention is formed of a single flexible sheet metal band 10 which is coiled up into ring fi form, and is of a height to fit between the Serial No. 490,37.

burner and the grid of a gas range. The ends of the band overlap when it is formed into a ring, and each end is provided at the upper and lower edges with projecting cars 12 and 13, which are adapted to over- 60 lap the corresponding edges of the adjacent part of the band or ring. As a result the flexible band can be made larger or smaller as desired, and the ears 12 and 13 doubled over upon the adjacent part and pressed firmly to place, so that the size of the ring remains fiXQCh These ears 12 and 13 can be left sticking out at right angles to the body of the band, as shown by dotted lines in Figure 3, so that when the band is partly coiled, the end portions will slide through the pairs of ears and when the right size is determined, the ears can be bent down as stated. This size is of course dependent on the burner 17 to which the ring or band is to be fitted, and the'ring is formed of such a size as to enable it to be pressed snugly upon the burner, and it can be applied to burners of any usual type.

The ring or attachment is provided near the lower edge and on the part which is not ordinarily overlapped, with air holes 14, and the parts of the ring or band which overlap each other are provided with elongated slots 15 which can be arranged so as to register more or less as required, thus regulating the openings for the admission of air.

When the attachment is adjusted to fit snugly on the burner and is applied thereto, the air will flow in through the openings 14 and 15, and will assist in the combustion of gas, and will mingle therewith in the usual and well known way, so that a comparatively little amount of gas will furnish the requisite heat because of its good admixture with air, and more particularly because it is confined by the ring 10 and directed so as to impinge upon the article to be heated.

From the foregoing description it will be 109 I seen that I have devised an attachment of the utmost simplicity of construction, which can be instantly adjusted as to size, which can be easily applied to the burner, which has the air openings in the right place to 1 assist combustion, and which undoubtedly! conserves the gas.

I claim A gas burner attachment comprising a ring formed of a single flexible metallic by said slots can be brought into registry when the band ends are overlapped.

Signed at New York, in the county of 10 New York and State of New York, this 1st day of August, A. D. 1921.

WILLIAM R. GARDNER.
